INIPROV'EMENT IN GAMING-ENGINES.

Sche'iule referred to in these Letters Patent and making nait of the" name.

To all whom it may concern Be it known that I, BARTON H. Janus, of lrides, burg, in the county of Philadelphiaand State of Penn' sylvania, have invented a new and useful Improvement on Gaining-Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,mak ing apart of this speciication,` in `which-- Figure 1 is a side view of one endofa small roller cfa cotton or wool-carding engine,V showing the imfibres of cotton or wool 'shall not be allowed'to fall upon the gudgeons of said rollers,or find lodgment between theends of the rollers and their bearings. l

The nature of my invention consists in supporting theends ofthe shaftsof carding-rollers or cylinders upon adjustable poppet-heads, by means of stationary sleeves which pass through the sides of the frame of the machine, and abut snugly against the ends of the v heads of said card-rollers or cylinders, thereby leaving the ends of 'the latter exposed, and at the same time covering the shafts or gudgeons, so as to preclude lint `or fibre, as will be hereinafter explained.

`'.llo enable others skilled in` the art to understand my invention, I will describe its construction and operation'. Y

In the accompanying drawingsv A represents an uncovered portion of a card-cylinder, or roller, which,in practice, is covered with cardwire, and' arranged within the frame A2 of the engine, so as to operate in conjunction with a large cardingcylinder.

This cylinder is constructed upon heads A1, 'which are keyed fast upon a central shaft, 0,'as shown in iig. 3, and the ends of this shaft extend beyond the ends ofthe cylinder far enough to project through the sides of the frame A, and be supported by 4adjustable bearings, secured upon said sides.

The heads A1 are constructed with outwardly-projecting hubs B, which abut snugly against the inner ends of tubularbearing or sleeves D, 'so that the cylinder will begprevented fromreceiving end-play while in operation. y t

- The drawing represents one end of the card-cylinder A and its supportingdevices, and as the devices Ywhich support its opposite end are precisely like those shown Mpcin the drawings, I will conine my description' of them a hole through it, for receiving a bolt, c.

fined between the jaws of a stud, J, that is fastened to one end only.

The sleeve D is constructed so'as to receive and en close all that portion of the shaft G which extends be- -yond the hub B of cylinder-head A1, and in this sleeve the shaft C'turns freely.

The opposite sides of sleeve D are flattened, as shown at fj, fig. 4,-for the purpose of fitting it between jaws E', which areformed on the upper end of an adjustable poppet-head or bearing, E, which jaws prevent said l sleeve from turning with its shaft O.-

The head E is -secured to a supporting-plate, F, which is bolted upon the outside of the frame A, and which is constructed with side-ears a, a, andalso-with "Set-screws b b are tapped through the ears c a, and abut against the sides of the head E, as shown in fig. 2, by means of which thisheadcan'be adjusted and set laterally in any desired position.

The bolt c passes through an oblong slotfh, made through the face of the head E, and receives upon i'ssy screw-tapped end a nut, d, by loosening which latter, this head E-can be adjusted-in thedirection of its v length.l

The perforated nut G, upon a screwfstem, e, which is pivoted to the lower end of the poppet-head E,.is designed to assist in adjusting this head in a direction with its length, for which piu-pose the nut G is conto the frame A, as shown in gs. 1, 2, and 3.

The stand or poppet-head which receives the safetysleeve D is made adj nstable, for the purpose of allowing the card-wire upon the cylinder A to be set to work in proper relation to the card-wire upon themaincylinder, and to keep the carding-surfaces in proper relation to each other after they have been dressed or sharpened. l Y y For these reasons I have described, and prefer to employ, a puppet-head made adjustablesubstantially as described, -for supporting and holding the improved safety-sleeve. Y l

In carding-engines heretofore made, an attempt has been made to prevent the occurrence of iire, by pro-l viding the strippers, workers, and licher-in cylinders with caps, which were adapted to receive the ends of said cylinders, and which were applied to stationary bearings, but it is found that thev fibres of wool and cotton will will work between these caps andthe ends of the cylinders, and increase the liability of 4'firek la f The invention which I have above described,effectu` g ally prevents the cotton or wool, as the case may be, from falling 'upon the shaft C, or working betw en "moving surfaces, and consequently there can be no l bilityof fire taking place from the cause above tioned. j .p p I do not confine myinvention tothe cylinder "of cotton-cards, as it is aippliable to and'will be found valuable as a means of safety for the cylinders of all kinds of machinery which is required in working or treating highly-inflammable substances, and which is .ex'posed .to danger in the manner above stated.

Having described my invention, l

What I claim as new, and desire to secure by Letters Patent, is

In eombinaton with a poppet-head, the shaft C, 'the cylinder A, the flanged sleeved head A1 B, set within the cylinder, and the sleeve D, with its end abutting against hub B, the cylinder, flanged sleeved hea-d, and sleeve, being constructed and arranged as shown.
